February 22, 201313 yr Author That Command Timeout stayed the same before and after the LONG smart test. They must have accumulated while attached to the ARC1200. Googling pointed to a bad connection. I used the same cables when attaching the disks to the motherboard when I ran the LONG smart test. Maybe the cable was or became loose when attached to the ARC 1200. Wish I could run the LONG smart test while attached to the ARC 1200. http://kb.acronis.com/content/9123
February 23, 201313 yr Author Small update: I have reseated the SATA cables on the ARC1200, after checking and double-checking the connectors on both cables and ARC1200. Didn't find any anomalies. Put the card back on the mainboard. I have changed some settings in the cards BIOS, spindows to 60, time to low rpm etc to disabled. I ran a parity build overnight that just finished after 12 hours, without problems, now running a parity check: @ 3%, 75MB/sec.
February 23, 201313 yr I was just comparing the 2 SMART reports and noticed that one drive has a high Command Timeout: 188 Command_Timeout 0x0032 100 099 000 Old_age Always - 4295032849 while the other doesn't: 188 Command_Timeout 0x0032 100 094 000 Old_age Always - 105 What does that indicate? Loose connection? Good catch, Frankly, I don't know the answer. I would suspect the cable, but I did not see any DMA CRC errors, do a google search and see what it returns. These values are are fine. The RAW_VALUEs have meaning only to the manufacturer, e.g., the RAW_VALUE may be a bit mask rather than a cardinal number. They both have perfect VALUEs of 100. The first one had a VALUE of 99 some time in the past and the second one had a VALUE of 94 some time in the past. The second one, with a RAW_VALUE of 105 and a WORST value of 94, was worse off than the first drive. This is counter to the given arguments in that the disk with a value of 105 appears to have had a worse past.
February 23, 201313 yr Author Dang, thought I had found something. Let us see how it goes now. Hard to interprete these SMART values. Thanks so far guys!
